Search can be used as a wedge in a variety of ways. Most are perhaps poorly understood by the media and market regulators.

Woot! Check Out Our Bundling Discounts

When Google Checkout rolled out, it was free. Not only was it free, but it came with a badge that appears near AdWords ads to make the ads stand out. That boosts ad clickthrough rates, which feeds into ad quality score & acts as a discount for advertisers who used Google Checkout. If you did not use Google's bundled services you were stuck paying above market rates to compete with those who accepted Google's bundling discounts.

This Brand is Your Brand, This Brand is My Brand

Companies spend billions of Dollars every year building their trademarked brands. But if they don't pay Google for existing brand equity then Google sells access to that stream of branded traffic to competitors, even though internal Google studies have shown it causes confusion in the marketplace.

The Right to Copy

Copyright protects the value of content. To increase the cost of maintaining that value, DoubleClick and AdSense fund a lot of copy and paste publishing, even of the automated variety. Sure you can hide your content behind a paywall, but if Google is paying people to steal it and wrap it in ads how do you have legal recourse if those people live in a country which doesn't respect copyright?

You can see how LOOSE Google's AdSense standards are when it comes to things like copyright and trademarks by searching for something like "bulk PageRank checker" and seeing how many sites that violate Google's TOS multiple ways are built on cybersquatted domain names that contain the word "PageRank" in them. There are also sites dedicated to turning Youtube videos into MP3's which are monetized via AdSense.

Scrape You Very Much

Philosophically Google believes in (and delivers regular sermons about) an open web where companies should compete on the merit of their products. And yet when Google enters a new vertical they *require* you to let them use your content against you. If you want to opt out of competing against yourself Google say that is fine, but the only way they will allow you to opt out is if you block them from indexing your content & kill your search traffic.

“Google has also advised that if we want to stop content from appearing on Google Places we would have to reduce/stop Google’s ability to scan the TripAdvisor site,” said Kaufer “Needless to say, this would have a significant impact on TripAdvisor’s ranking on natural search queries through Google and, as such, we are not blocking Google from scanning our site.”

From a public relations standpoint & a legal perspective I don't think it is a good idea for Google to deliver all-or-nothing ultimatums. Ultimately that could cause people in positions of power to view their acts as a collection which have to be justified on the whole, rather than on an individual basis.

Lucky for publishers, technology does allow them to skirt Google's suggestions. If I ran an industry-leading review site and wanted to opt out of Google's all-or-nothing scrape job scam, my approach would be to selectively post certain types of content. Some of it would be behind a registration wall, some of it would be publicly accessible in iframes, and maybe just a sliver of it is fully accessible to Google. That way Google indexes your site (and you still rank for the core industry keywords), but they can't scrape the parts you don't want them to. Of course that means losing out on some longtail search traffic (as the hidden content is invisible to search engines), but it is better than the alternatives of killing all search traffic or giving away the farm.
